We will put a defumidifier that generates 390W of heat in the EYV room if approved. We will also decrease the heater power by 300W in the Sunrise heater.

[Hayakawa, Sawada, ...]

A defumidifier whose power was 390W was put in the EYV area. To compensate the heat generation in the EYV room, I reduced the Sunrise heater power from 900W to 600W by 300W.

The following is the detailed process,

• 09:39 Mine IN
• ... No record
• 10:09 Yend1F IN
• 10:11 Yend1F OUT
• 10:15 EYV IN
• 10:23 EYV OUT
• 10:27 Yend1F IN
• 10:30 Yend1F OUT
• 10:44 Center IN
• 10:51 Center OUT
• 10:54 Mine OUT

I turned off the Sunrise heater because the temperature in EYV increased by 0.2 °C for 2 hours after turning on the defumidifier.

Fig.1 shows the temperature changes in the EYV and the humidity changes.

The temperature seemed to recover, and the humidity reduced to ~ 62 % level.
